Researchers create artificial materials atom-by-atom

Researchers have manufactured artificial materials with engineered electronic properties. By moving individual atoms under their microscope, the scientists were able to create atomic lattices with a predetermined electrical response. The possibility to precisely arrange the atoms on a sample bring ‘designer quantum materials’ one step closer to reality. By arranging atoms in a lattice, it becomes possible to engineer the electronic properties of the material through the atomic structure.
